[email protected] The nomenclature of the non-marine molluscs of the Seychelles islands (western Indian Ocean) as used in the 2006 treatise by Gerlach is critically reviewed. Notes are given regarding the use of brackets, publication dates, spelling of species-group names, overlooked genus-group names, and overlooked homonyms and synonyms in species-group names. A revised bibliog- raphy is presented. The Philippine species Steatodryas cepoides should be called Pachya cepoides; the European species now known as Petasina unidentata (Draparnaud, 1805) should be called Petasina monodon (A. Férussac, 1807). For Edouardia sensu auctt. (non Gude, 1914), a group of taxa living in Africa, Madagascar and India, the name Gittenedouardia is introduced. The nomen novum Annularia rosenbergi is introduced for the Jamaican species Turbo pulcher W. Wood, 1828 nec Dillwyn, 1817. Key words: Gastropoda Pulmonata, Acavidae, Stylodonta, Bradybaenidae, Pachya, Steatodryas, Hygromiidae, Petasina, Cerastidae, Conulinus, Edouardia, Gittenedouardia, Annulariidae, Annularia, synonymy, nomenclature, Seychelles, Philippines, Africa, India, Madagascar, Europe. INTRODUCTION Taxonomy (and thus biology as a whole) needs a universal and unambiguous lan- guage for the designation of taxa, and this language is provided by the codes of nomen- clature.
